wooo-DRYING KILN.

SPECIFICATION forming part of Letters Patent Ne. 388,102, dated August 21, 1888.

Application filed September 9, 1886. Serial No. 213,136.

To all whom, it may concern.-

Beit known that we, AncALoUs Wvcitorr and ERNns'r L. Wroiforiv, of Elmira, in the county ot' Ghemung and State of New York,

have made certain new and useful Improvements in IVood-Drying liilus, of which we declare the following to be a full, clear, and concise spccitication.

Our invention relates to improvements in 1o wood-drying kilns; and the novelty consists in a kiln of the class named, having an iuclosed chamber to receive the material to be dried, a series of inclined deilectors or tables by which saidi material is more fully exposed I5 to the action of heat within said chamber, a series ofcirculatiiig-pipes adapted to be heated by steam,and means to cause currents of heated air to pass to and through the inclined deiiectors and the material thereon, all substantiall y as hereinafter set l'orth,and illustrated in the accompanying drawings, wherein similar figures of reference denote similar parts.

In said drawings, Figure l is a side elevation of a kiln constructed in accordance with our invention. Fig. 2 is a central longitudinal section therethrough. Fig. 3 is a transverse section through said kiln, and Fig. 1 is a plan view thereof.

In the present embodiment of our invention 3o we provide a chamber, 1, which is formed within a shell or casing, 2, constructed of any desired suitable matcrial-as stone, brick,slate, iron, &c.-with two main or principal deflecting-tables, 3, which are formed of a series of slats, 4, that extend from longitudinally-extending rails 5,secured to opposite sides of the chamber 1, at or near the bottom thereof, upward and inward to a rail, G, at or near the middle of the chamber 1.

Immediately above the deiiectors 3, and below the middle of the opening 7,through which the kiln is charged, we arrange a second pair of defiectors, S, which are smaller than and have a similar construction to the tables 3,and are supported upon rails 9 and 10, which extend from end to end ofthe chamber, and struts or braces 11,whieh abut upon the ridge or apex of the tables 3 and extend thence to the rails 9 and 10, respectively.

IVe provide the opposite surfaces of the (No model.)

chamber 1 in the plane of the tables 8 and the middle ofthe tables 3 with outwardlydnclined tables 12 and 13, which are formed in manner similar to the tables 3 and 8,and are supported by rails 14 and 15 and struts 1G and 17. IVe 55 arrange a series ot' dellectors, 1S and 19, at points intermediate of the deilectingtables hereinbel'ore described, each of which dellectors consist of oppositely-inclined tables 20 and 2i, supported upon rails 22 and struts 23.

By reference to Fig. 2 it will be observed that the tables 20 would, if extendedhjoin the tables S and 12 at or near the middle of the latter, while said latter tables would, if extended, join the tables 2i immediately below 65 the junction of said table, while the latter are arranged, as regards the tables 13 and 3, in manner similar to their fellows, as above described.

By the described construction or arrange- 7o ment of the several detlecting-tables, material, and particularly kindlingwood, which the chamber 1 is designed and adapted to receive, would, if thrown upon the upper detlectors, pass downward from table to table until it reached apertures 21, formed through the opposite sides of the easing 2, immediately above the junction of the tables 3 therewith, for the purpose of removing the material from the kiln.

It will also be apparent that the kindlingwood will, in its passage from top to bottom of the chamber 1, be thrown about, and so be fully exposed to the action of heat generated within said chamber by a series ol" steaiu-receiving coils or pipes, 25 and 2G, which are located beneath the tables 3 and 13, respectively.

A constant circulation of air is maintained within the chamber 1 by either a blast-fan or blower, 27, connected with the bottom of the 9o chamber 1, or an exhaust-tan, 28, connected with the upper portion of said chamber.

It will be understood that moist vapors from the wood will pass to and escape through a ilue, 29, with which the kiln is provided.

It desired, the openings 2l may extend from end to end of the chamber 1, as shown by full lines in Fig. 1, or a series olY smaller openings may be formed; also,said openings may be provided with flaps or doors 30, as shown in Fig. roo

3. When the openings 24 are small, as shown by the dotted lines in said Fig. 1, a series of inclined tables, 31, which are arranged perpendieularly to the tables 3, may be employed to delect the wood to such openings.

In practice steam is admitted to the coils 25 and 26,to heat the interior of the kiln, after which kindling wood, which consists, as is well known, in small pieces of wood, is admitted to the chamber 1 through the opening 7, and, falling to the deflectors or inclined tables, is diverted from a direct downward course and passed back and forth from table to table until it reaches the discharge-openings 24.

It will be understood that the position of the wood while passing down the inclined tables will be changedthat is t0 say, that portion of the wood which was underneath upon the one table will be upon the top upon the next lower table; also that such change of position ofthe wood will continue until the lowest limit of movement is reached thereby.

We have herein described and prefer to heat ythe chamber l by steam, which is admitted to the pipes or coils 25 and 26, as we have found such method to be the best in practice. If desired, however, heated. air may be used in said pipes in lieu of steam.

If desired, a damper may be arranged within the iue 29, as indicated at 32.

If desired, the chamber 1 may be charged through the iiue 29.

It will be seen that the two main dell ectingtables extend high up into the chamber,` the heating-coils being arranged nearly or quite to the upper portion thereof, and that the inclined tables 13 (beneath which are steamcoils) are opposite the main tables 3, while between these tables, beneath which are placed the heating-coils, are arranged the deflectors 19 and 21, which insure that the wood shall be caused to travel over practically the whole surface of these tables, in close proximity to which are the heating-coils. By this arrangement we have found that a most thorough exposure of the wood to the drying heat is 0btained in a device wherein the material passes automatically through the drier.

The tables 13 eventually deliver the material which has been exposed thereon to the main tables 3, which terminate opposite the delivery-openings 24.

Various modifications in detail of construction may be made inthe within-described invention without departing from the spirit thereof, which contemplates a drying-chamber heated by a series of steam-receiving coils or pipes and provided with inclined deiieetors, which are arranged to permit the passage of heated air therethrough to and about the material thereon.

Ve claim-- l. Inakiln for dryingkindling-wood,acasing having an inclosed chamber and an exhaust ing apparatus for taking away air and vapor from the top thereof, in combination with main detlectiug slatted tables 3, situated in the lower part of the chamber, heating-coils arranged beneath the tables, inclined slatted tables 13, situated at the sides of the chamber opposite tables 3, other heating-coils arranged beneath tables 13, and inclined deflectors of inverted- V shape, also of slats, and arranged to direct the material to the said tables and to form open spaces throughout the mass of wood being dried, and means for furnishing air to the heaters, whereby it is irst heated and then passed through the entire mass of wood, the slatted tables and deeetors facilitating such passage, substantially as set forth.-

2. `A easing inclosing a chamber, 1, having openings 24 formed at its opposite sides, and oppositely-iuelined tables 3, formed of slats 4, terminating opposite said openings, in combination with a series of smaller grated inclined dellectors arranged above and at the sides of said tables 3 and delivering thereon, and a series of steam-receiving pipes or coils below each of said tables, and an exhaust fan or blower, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subcribing witnesses.
